1.14 A sample of methane of mass 4.50 g occupies 12.7 dm3 at 310 K. Calculate the work done when the gas expands (a) isobarically against
a constant external pressure of 30.0 kPa until its volume has increased
by 3.3 dm3, and (b) isothermally by 3.3 dm3.

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
